hrtng IDA Plugin : Elevating IDA’s Capabilities For Advanced Malware Analysis

hrtng IDA plugin is a collection of tools, ideas and experiments from different sources I’ve found interesting and useful in my reversing work.

A practical guide to the reverse of a complex malware using the example of dissecting a FinSpy module with help of hrtng IDA plugin on securelist

There is no one place in menu where all functionality of the plugin grouped together. hrtng menu items placed closer to logically related standard IDA & Hex-Rays decompiler functions. Messages, menu items, popup windows and dialog boxes belong to this plugin are marked with “[hrt]” prefix.

The plugin requires Hex-Rays decompiler presence in your IDA installation. The plugin can be compiled with IDA SDK >= 7.3 but not well tested with old versions.
